Abstract

Object of the present invention is a process for preparing vinylidenefluoride (VDF) polymers which comprises polymerizing VDF, optionally in association with other fluorinated olefins, in an aqueous medium in the presence of a radical initiator and of 1,1,1-trifluoro-2,2-dichloroethane (HCFC-123) as chain transfer agent. A final product with very good colour characteristics (appearance), substantially devoid of discoloration effects at high temperatures, is so obtained.
